Tidal on Oppo 105

I've been using an EVS modded OPPO BDP105 for the past two years as my system DAC.   Mainly playing saved wav and flac files on a solid state hard drive I have connected to it as well as playing music from Tidal which I stream through the Oppo.    Using the Oppo App on my I pad the whole arrangement works really well.   I am able to switch back and forth between my saved music and Tidal with ease.

I have the upgrade bug again, however, and am starting to look for a new DAC.    My question is would it be worth it to spend some serious money on a dedicated Digital Player(Bryston BDP or on of the Aurender products) or just use that money on the DAC itself -- Outputing from my OPPO to the DAC.  Would love to stay under $5k if possible.

Any thoughts are much appreciated.
